来源:http://www.jnmcd.com 发布时间:2019-04-29 浏览:
由于体积和电刷换向器的限制,直流电动机的转速普通在3000-12000转/分范围内,转速增加,电动机的工作寿命将显著降低。
Due to the limitation of volume and brush commutator, the speed of DC motor is generally in the range of 3000-12000 rpm. With the increase of speed, the working life of the motor will be significantly reduced.
采用的精细低噪音电动机,内部装有压敏电阻,以减少对环境的电磁干扰。
The fine low noise motor with varistor is used to reduce electromagnetic interference to the environment.
电动机的工作寿命主要取决于电刷和换向器的机械磨损和电化学腐蚀,在额定的负载转矩和速度条件下,可连续运转300到500小时。
The working life of the motor mainly depends on the mechanical wear and electrochemical corrosion of the brush and commutator. Under the rated load torque and speed conditions, the motor can run continuously for 300 to 500 hours.

齿轮电动机是电动机和齿轮箱的组合件。用户在选用电动机时,常常会由于电动机的转速太高或转矩太小而不能满足需求,此时,选用齿轮电动机是最适宜和最直接的计划。
Gear motor is a combination of motor and gear box. When users choose motor, they often can not meet the demand because of the high speed or small torque of the motor. At this time, selecting gear motor is the most appropriate and direct plan.
超颖科技有限公司消费的微型直流齿轮电动机选用最常用的直流电动机,齿轮箱的直径从12到37mm,以及大直径48mm的梨形等,应用于电压1.5伏到24伏、功率10瓦以下、转速在每分种1转到数十转、转矩在30公斤厘米以下的普遍范畴。
Miniature DC gear motors consumed by Chaoying Technology Co., Ltd. are the most commonly used DC motors. The diameter of gearbox ranges from 12 to 37 mm, and the pear shape with a large diameter of 48 mm. They are used in the general fields of voltage from 1.5 volts to 24 volts, power below 10 watts, rotational speed from 1 to tens of rotations per minute, and torque below 30 kilograms centimeters.

齿轮电动机的计算
Calculation of Gear Motor
转速n=nm÷i (rpm)nm-电动机转速,i-齿轮箱总齿数比。
Speed n = nano_i (rpm) nano - motor speed, I - gear box total teeth ratio.
转矩T=Tm×i×ηg÷1000 (kgcm)Tm-电动机输出转矩(gcm),i-齿轮箱总减速比,ηg-齿轮箱总效率(%)。
Torque T = Tm x I x_g_1000 (kgcm) Tm-motor output torque (gcm), i-gearbox total deceleration ratio, _g-gearbox total efficiency (%).
齿轮箱总效率ηg=η1×η2×η3×η4???η1-第一级齿轮副效率,η2-第二级齿轮副效率,η3-第三级齿轮副效率???,每级齿轮副效率约95%。
The total efficiency of gearbox g = _1 *2 *3 *4???? 1-first gear pair efficiency, 2-second gear pair efficiency, 3-third gear pair efficiency????? The efficiency of each gear pair is about 95%.
输入功率P1=U×I (W) U-电压(V),I-电流(A)。5.输出功率P2=T×n÷
Input power P1 = U * I (W) U - voltage (V), I - current (A). 5. Output power P2=T*n_
转矩(kgcm),n-转速(rpm)。

齿轮电动机总效率η=P2÷P1×100=ηm×ηg(%),ηm-电动机效率。
The total efficiency of gear motor_ = P2_P1 *100 = _m *g(%) and_m-motor efficiency.
齿轮箱的构造和特性
Structure and Characteristics of Gear Box
直流齿轮电动机的负载转矩对转速、电流有着直接的关系,转速随负载的增大而线性降低,电流则线性增加。选用规格时,应尽量在其最大效率点左近工作,以取得理想的运转性能、工作寿命和特性稳定性。
The load torque of DC gear motor has a direct relationship with the speed and current. The speed decreases linearly with the increase of load, while the current increases linearly. When choosing specifications, we should work as close as possible at its maximum efficiency point in order to achieve ideal operation performance, working life and characteristic stability.
通常,直流齿轮电动机的运用环境与微型直流电动机相同,如有特殊需求,例如环境温度、过载条件、电流限定等,必需事前阐明。
Usually, the operating environment of DC gear motor is the same as that of micro DC motor. If there are special requirements, such as ambient temperature, overload condition, current limitation, etc., it must be clarified beforehand.
齿轮箱的工作寿命普通超越直流电动机的工作寿命,通常能够到达1000到3000小时。
The working life of gearbox usually exceeds the working life of DC motor, and can usually reach 1000 to 3000 hours.
齿轮箱的总减速比普通在1:10到1:500范围内。经过特殊设计,能够到达1:1000或更大,但很大减速比的齿轮箱不允许"倒转",即不能以齿轮箱的输出轴作为主动轴,强行倒转。
The total deceleration ratio of gearbox is between 1:10 and 1:500. After special design, the gear box can reach 1:1000 or larger, but the gear box with a large reduction ratio does not allow "reversal", that is, the output shaft of the gear box can not be used as the driving shaft to force reversal.
